Kernel 4.8

Сообщение euspectre » 31 окт 2016, 11:25

The packages with kernel 4.8 are now available in the unofficial repositories:

64-bit: http://abf-downloads.rosalinux.ru/kerne ... 8/release/
32-bit: http://abf-downloads.rosalinux.ru/kerne ... 8/release/

If you would like to try it, see http://wiki.rosalab.ru/en/index.php/Ins ... al_kernels for the installation instructions.

You might also want to enable x11_backports repository for graphics updates, etc.

Note that, as usual with the unofficial kernels, the proprietary drivers are not guaranteed to work with kernel 4.8.x yet, but some of these may work.

X64 desktop Version.
Strange behavior for me: Kernel 4.8 allows me to log-in, but then I only see the desktop background: it looks like KDE does not start. The only possible action is to move the mouse pointer around or press the reset on the pc. Back to 4.7 and everything is back.

Could you try to boot kernel 4.8 again, log in, wait till the problem happens, then switch to a virtual console (e.g., ctrl-alt-f2) and send us the info about the system as well as the logs with hw-probe tool (http://hw.rosalinux.ru/index.php?show=check)?

Thank you for your quick answer.
Unfortunately. pressing [ctrl-alt-F2] does not take me to a working console, but only to the screen shot that you can see in the two attached pictures. Substantially the image remains the same over the time and only from time to time it is updated, but only the leftmost numbers change. The two pictures have been taken at approximately 30 minutes of distance.

Anything else I can do to try to help you?

There were errors before these ones, it seems, and the first ones are usually the most meaningful.

Could you try the following. Try to boot with the kernel 4.8.x again, wait till the problem happens.

Then, if your keyboard has SysRq key, press alt-sysrq, then (while keeping alt-sysrq pressed) - 'R', 'E', 'I', 'S', 'U', 'B'. The system may reboot as a result, which is OK. If it does not reboot, reboot it manually.

Now boot with the kernel 4.7.x that worked for you. Then, please run hw-probe tool I mentioned earlier to upload the hardware info and the logs to us. hw-probe will try to collect the logs from the previous boot as well. So, if we are lucky, we will get more info about that system crash and lockup.

Thank you for your answer.
I am currently out of home, and I will supply you the hw-probe output on Thursday or Friday, as soon as I am back.
In any case I am now writing from my laptop, a Dell Precision M6300 on which kernel 4.8 runs just smoothly.

OK, I sent you the hw-probe output. I had to force an hardware reset to reboot.

Thank you for your help

Ah, I suppose you saved the URL output by hw-probe? Could you post it here or send it to me in a private message? Without it, we cannot find it among the probes from several thousands of machines.

Thanks for the info.

I see now, looks like this is the same problem with 'wl' driver for Broadcom WiFi adapters some other our users encountered not long ago with kernel 4.8. Hopefully, I will have time for it in a day or two.

In the meantime, you can either continue to use kernel 4.7.x or you can remove dkms-broadcom-wl - the system will try to use the in-kernel opensource driver for that WiFi adapter instead.

Thanks for your help. I guess I'll stay on kernel 4.7 for a while and switch to 4.8 when your solution will be available

Please try this build of broadcom-wl, it should support kernel 4.8 too:
http://abf-downloads.rosalinux.ru/rosa2 ... x86_64.rpm

This version has been working OK on our test systems so far.

It seems, 4.8.17 will be the last version in 4.8.x kernel series.

Work on 4.9.x is under way. The packages with kernel 4.9.1 are already available, although *almost completely* untested yet. Still, they seem to work on 2-3 machines we have tried them so far.

Note that the proprietary drivers may or may not work, it will take time to check all that.

Anyway, the repositories for the kernel 4.9.x are in the usual locations:
64-bit: http://abf-downloads.rosalinux.ru/kerne ... 9/release/
32-bit: http://abf-downloads.rosalinux.ru/kerne ... 9/release/

If you are curious, you can give kernel 4.9 a try - or wait a bit before at least version 4.9.2 arrives with 100+ fixes. It is expected to be released soon.

As usual when trying a new kernel, please upload the data using hw-probe to us.
